# Linkdr Design System

**Version 1.0** · derived from the wix.com design language, adapted for Linkdr.

This document is the single source of truth for how Linkdr looks. Every screen must be
buildable from the tokens and components below. If a screen needs something that is not in
here, add it here first, then build it.

## Provenance and scope

The visual language is adapted from **wix.com** (sampled 2026-08-21): the Madefor typeface
pair, the signature action blue, the navy-black ink, the pill geometry and the generous
whitespace rhythm. Values below were read off the live stylesheet, not eyeballed.

Adopted: typefaces (Wix Madefor Display / Text, published under the SIL Open Font License via
Google Fonts), colour ramps, radius and spacing conventions, component geometry.

**Not** adopted: Wix's logo, wordmark, product names, illustrations or photography. Linkdr is
not affiliated with Wix and must never present itself as such.

## 1. Principles

0. **Mobile only.** One column, one container, thumb-reachable actions, no desktop layout and
   no marketing site. See §4 — this constrains every other decision here.
1. **Blue means action.** `brand-500` is reserved for things the user can do. It is never
   decoration, never a background wash for a whole section, never body text.
2. **Ink is near-black, not grey.** Headings sit at `ink-950` (`#000624`) — black with a blue
   cast. Grey text is a deliberate demotion, not a default.
3. **Type carries the design.** Big, tight display type over ornament. Negative tracking on
   anything above 24px; zero tracking on body.
4. **Pills for actions, soft rectangles for containers.** A pill is clickable. A rounded
   rectangle holds content. Never the reverse.
5. **Whitespace over borders.** Separate with space first, a hairline second, a shadow last.

---

## 2. Colour

All values are sampled from wix.com. Hex is normative.

### 2.1 Brand — action blue

| Token | Hex | Use |
|---|---|---|
| `brand-50` | `#EDF3FF` | Hover fill on ghost / outline controls |
| `brand-100` | `#DCE8FF` | Selected-chip fill, info banner background |
| `brand-200` | `#95B9FF` | Focus ring halo, disabled primary |
| `brand-400` | `#5E97FF` | **Dark-mode** link and accent text |
| `brand-500` | `#116DFF` | **Primary action.** Buttons, links, active states |
| `brand-600` | `#094BCC` | Primary hover / pressed |
| `brand-700` | `#082F7B` | Primary active on dark surfaces |

`brand-500` on white is **4.5:1** — it clears AA for normal text, but only just. Do not tint it
lighter for text. On dark surfaces use `brand-400` (7.0:1 on `ink-950`) instead.

### 2.2 Ink — text and surfaces

| Token | Hex | Use |
|---|---|---|
| `ink-0` | `#FFFFFF` | Card surface, page background (light) |
| `ink-50` | `#F7F8F8` | Alternating section background |
| `ink-100` | `#F0F0F0` | Inset fills, skeletons, track backgrounds |
| `ink-200` | `#E2E2E2` | **Hairline borders** |
| `ink-300` | `#C2C2C2` | Border on dark, disabled border |
| `ink-400` | `#B0B0B0` | **Dark-mode** secondary text |
| `ink-500` | `#8F8F8F` | Placeholder and disabled text **only** (3.2:1 — never body copy) |
| `ink-600` | `#6E6E6E` | **Secondary body text** (5.1:1 on white) |
| `ink-800` | `#212121` | Body text on tinted surfaces |
| `ink-950` | `#000624` | **Headings, primary text, dark surfaces** |

### 2.3 Semantic

| Token | Hex | Meaning |
|---|---|---|
| `go-50` | `#F3F8F0` | Success banner background |
| `go-100` | `#D2E4C7` | Success border |
| `go-400` | `#92B079` | Success on dark |
| `go-600` | `#618741` | **Success** — verified, accepted, right-swipe |
| `go-700` | `#39641D` | Success pressed |
| `sun-50` | `#FFE9DF` | Warning / pending banner background |
| `sun-100` | `#FFBFA1` | Warning border |
| `sun-400` | `#FA854F` | Warning on dark |
| `sun-500` | `#EA6020` | **Warning** — pending review, expiring soon |
| `sun-600` | `#C94001` | Warning pressed |
| `stop-50` | `#FFECEC` | Error banner background |
| `stop-100` | `#FFC9CB` | Error border |
| `stop-400` | `#FF6A70` | Error on dark |
| `stop-500` | `#ED1C24` | **Error / destructive** — rejected, left-swipe |
| `stop-600` | `#C4141B` | Error pressed |

Never use green/red as the *only* signal. Pair with an icon and a word.

### 2.4 Dark mode

Dark mode inverts the ink ramp and lightens the accent. It is not a separate palette.

| Role | Light | Dark |
|---|---|---|
| Page background | `ink-0` | `ink-950` |
| Raised surface (card) | `ink-0` | `#0C1230` |
| Sunken surface | `ink-50` | `#070C22` |
| Primary text | `ink-950` | `ink-0` |
| Secondary text | `ink-600` | `ink-400` |
| Hairline | `ink-200` | `rgb(255 255 255 / .14)` |
| Accent text / link | `brand-500` | `brand-400` |
| Filled primary button | `brand-500` bg, white text | unchanged |

---

## 3. Typography

### 3.1 Families

| Role | Family | Weights |
|---|---|---|
| Display — h1–h3, big numbers, buttons | **Wix Madefor Display** | 400–800 variable |
| Text — body, labels, inputs, meta | **Wix Madefor Text** | 400–800 variable |

Fallback stack: `'Segoe UI', system-ui, -apple-system, sans-serif`.

Load via `next/font/google` with `display: 'swap'`, exposed as CSS variables. Never link a
stylesheet in `<head>` — it costs a render-blocking round trip.

### 3.2 Scale

Display sizes use `clamp()` so one token works from 360px to desktop.

| Token | Size | Line | Tracking | Weight | Family |
|---|---|---|---|---|---|
| `display-xl` | `clamp(2.75rem, 6vw, 4.5rem)` | 1.04 | `-0.03em` | 700 | Display |
| `display-lg` | `clamp(2.25rem, 4.5vw, 3.25rem)` | 1.08 | `-0.025em` | 700 | Display |
| `h1` | `clamp(1.875rem, 3.5vw, 2.5rem)` | 1.12 | `-0.02em` | 700 | Display |
| `h2` | `clamp(1.5rem, 2.5vw, 2rem)` | 1.18 | `-0.02em` | 700 | Display |
| `h3` | `1.375rem` | 1.25 | `-0.015em` | 600 | Display |
| `h4` | `1.125rem` | 1.35 | `-0.01em` | 600 | Display |
| `body-lg` | `1.125rem` | 1.55 | `0` | 400 | Text |
| `body` | `1rem` | 1.6 | `0` | 400 | Text |
| `body-sm` | `0.875rem` | 1.5 | `0` | 400 | Text |
| `meta` | `0.75rem` | 1.45 | `0` | 500 | Text |
| `overline` | `0.75rem` | 1.4 | `0.08em` | 700 | Text, uppercase |

### 3.3 Rules

- **One display element per view.** A page has one `h1`. A card has none.
- Tracking is negative above 24px and exactly zero below it. Never positive except `overline`.
- Body copy maxes at **68 characters** (`max-w-[68ch]`).
- Headlines use `text-balance`; paragraphs use `text-pretty`.
- Prices, counters and table figures use `tabular-nums`.

---

## 4. Space and layout

**Linkdr is a mobile-only product.** There is no desktop layout, no marketing site and no
responsive breakpoint work. Design for a 360–430px viewport and nothing else. On a wider
screen the app renders as a single 480px column centred on `ink-50` — that is a courtesy for
someone who opened it on a laptop, not a layout to design for.

Concretely, this bans:

- Multi-column grids. Everything is one column. A 2-up grid is allowed only for paired
  numeric fields (from/to, rate/years) and stat tiles.
- `md:` / `lg:` variants that change structure. Type already scales with `clamp()`.
- Sticky desktop nav bars with link lists, mega-footers, hero sections, feature grids.

An **8px grid**. The only legal spacing values are `4 8 12 16 24 32 40 56 72`. Anything else
is a bug.

| Token | Width | Used for |
|---|---|---|
| `app` | 480px | Every screen. There is no second container. |

- Page gutter: **20px**. One value, all screens.
- Vertical rhythm between blocks within a screen: **32px**. Between major groups: **40px**.
- Gap between sibling cards in a list: **12px**.
- Label → control: **8px**. Control → helper text: **8px**. Field → field: **24px**.
- Bottom of scroll content clears the tab bar by **88px** (`pb-22`) so nothing hides under it.

### 4.1 Safe areas

The tab bar and any fixed footer pad with `env(safe-area-inset-bottom)`. The app bar pads with
`env(safe-area-inset-top)`. Never assume the viewport edge is reachable.

---

## 5. Radius and elevation

| Token | Value | Applies to |
|---|---|---|
| `radius-pill` | `999px` | **All buttons**, chips, avatars, badges |
| `radius-card` | `18px` | Cards, banners, modals |
| `radius-lg` | `12px` | Inputs, list rows, small containers |
| `radius-md` | `8px` | Tags, thumbnails, inline code |
| `radius-deck` | `28px` | The swipe card only |

Elevation is restrained. Four steps, no more:

| Token | Shadow | Use |
|---|---|---|
| `shadow-none` | — | Default. Most surfaces are flat with a hairline. |
| `shadow-sm` | `0 1px 2px rgb(0 6 36 / .06), 0 1px 3px rgb(0 6 36 / .04)` | Hover on a list row |
| `shadow-md` | `0 4px 12px rgb(0 6 36 / .08), 0 2px 4px rgb(0 6 36 / .04)` | Sticky header, popovers |
| `shadow-lg` | `0 12px 32px rgb(0 6 36 / .12), 0 4px 8px rgb(0 6 36 / .06)` | Deck card, modal |

Shadows are tinted with `#000624`, never pure black.

---

## 6. Components

### 6.1 Button

Always a pill. Always Display family, weight 600. Label is sentence case, never ALL CAPS.

| Variant | Fill | Text | Border | Hover |
|---|---|---|---|---|
| `primary` | `brand-500` | white | none | `brand-600` |
| `dark` | `ink-950` | white | none | `#1A2145` |
| `outline` | transparent | `ink-950` | `1.5px ink-950` | `ink-50` fill |
| `ghost` | transparent | `brand-500` | none | `brand-50` fill |
| `danger` | `stop-500` | white | none | `stop-600` |

| Size | Height | Padding-x | Font |
|---|---|---|---|
| `sm` | 36px | 16px | `body-sm` |
| `md` | 44px | 24px | `body` |
| `lg` | 56px | 32px | `body-lg` |

Control heights are their own scale — **36 / 44 / 56** for buttons, **48** for inputs. They are
exempt from the 8px spacing grid in §4, which governs margins, padding and gaps.

- Minimum touch target is **44px**. `sm` is desktop-only or must sit inside a 44px row.
- Disabled: `opacity: .45`, `cursor: not-allowed`. Never grey out by swapping colour.
- Busy: leading 16px spinner, label unchanged, control disabled. Never replace the label.
- Icon-only buttons are circles and require `aria-label`.

### 6.2 Input, textarea, select

- `radius-lg` (12px), `1.5px ink-200` border, `ink-0` fill, **16px** text (never smaller — iOS
  zooms below 16px), padding `12px 16px`, height 48px.
- Focus: border `brand-500` + `0 0 0 3px brand-200`. Never remove the outline without
  replacing it.
- Error: border `stop-500`, message below in `body-sm` `stop-500` with `role="alert"`.
- Placeholder is `ink-500` and never carries meaning the label doesn't.
- Every control has a visible `<label>`. Placeholder-as-label is forbidden.

### 6.3 Card

`ink-0` surface, `radius-card`, `1px ink-200` hairline, `shadow-none`. Padding 24px (20px below
640px). Interactive cards raise to `shadow-sm` and shift the border to `brand-500` on hover;
they do not lift or scale.

### 6.4 Chip / selectable tag

Pill, `1.5px` border, `12px 16px` padding, `body-sm`. Unselected: `ink-200` border on
transparent. Selected: `brand-500` border, `brand-100` fill, weight 600, leading check icon.
Selection must never rely on fill alone.

### 6.5 Banner / status card

`radius-card`, 20px padding, 12px icon-to-text gap, tinted surface + matching border:

| Tone | Fill | Border | Icon |
|---|---|---|---|
| `info` | `brand-100` | `brand-200` | `brand-500` |
| `success` | `go-50` | `go-100` | `go-600` |
| `warning` | `sun-50` | `sun-100` | `sun-500` |
| `error` | `stop-50` | `stop-100` | `stop-500` |

Title in `h4`, body in `body-sm` `ink-600`.

### 6.6 App bar

Fixed top, **56px** plus top safe-area inset. `page` surface at 88% opacity with
`backdrop-blur(12px)` and a hairline bottom border.

Two layouts only:

- **Root screens** — screen title left in `h4`, at most one icon action right.
- **Pushed screens** — 44px back chevron left, centred title in `h4`, optional icon action right.

No link lists. No CTA button in the bar — the primary action lives in the screen or the tab bar.

### 6.7 Tab bar

Fixed bottom, **56px** plus bottom safe-area inset, `page` surface, hairline top border. Two
to five destinations, each a 44px-minimum target with a 24px icon over a `meta` label. Active
tab is `brand-500` icon + label; inactive is `ink-600`. The active state carries both colour and
weight, never colour alone.

The tab bar is the app's only persistent navigation. There is no footer.

### 6.8 Deck card

The one place that breaks the flat rule. `radius-deck` (28px), `shadow-lg`, full-bleed photo,
bottom scrim `linear-gradient(to top, rgb(0 6 36 / .92), rgb(0 6 36 / .35) 45%, transparent)`.
Overlay stamps: `SEND JOB` in `go-600`, `PASS` in `stop-500`, 4px border, ±12° rotation.

**The action row** is five circles, in one fixed order:

| | Action | Size | Ink |
|---|---|---|---|
| 1 | Rewind — bring the last card back | 44px | `ink-600` |
| 2 | Pass | **64px** | `stop-500` |
| 3 | Watch — tell me when they are free | 44px | `brand-500` |
| 4 | Send this job | **64px** | `go-600` |
| 5 | Ask a question | 44px | `ink-950` |

Two sizes, and the size *is* the hierarchy: the two decisions that end the card
are 64px and reach the thumb first; the three that do not are 44px — still the
minimum target from §8, never smaller. Gaps are 16px between a small and a large,
24px between the two larges, so the pair still reads as the pair.

All five are 2px bordered circles on `ink-0`. A control whose state persists —
watch — fills with its own colour when active, and its label changes with it;
selection is never carried by fill alone (§8).

Rewind is `disabled` with nothing to undo rather than hidden. A row that changes
length as you swipe moves the two buttons underneath your thumb.

---

### 6.9 Search field

The §6.2 input, 48px, with a 20px `Search` glyph inset 16px from the left in `ink-500`, and a
44px circular clear button on the right that exists only while the field has content.

The label is **visible above the field**, never the placeholder — §6.2 applies here more than
anywhere, because a placeholder disappears at exactly the moment someone needs reminding what
the box searches. The placeholder carries examples of what to type, not the name of the field.

### 6.10 Result row

`radius-card`, `1px ink-200`, `raised` fill, 16px padding, **12px between rows**. A 56px
`radius-md` thumbnail leads; where there is no image, its initial on an `inset` fill — never an
empty grey square. Title in `h4`, one `body-sm ink-600` line, one `meta` line of figures in
`tabular-nums`, trailing chevron in `accent`.

Hover and press move the border to `brand-500`. Rows do not lift, scale or shadow: a list of
twenty is a scanning surface, and twenty things that react is noise.

A row is **not** a deck card. The deck card is a single-decision object with its own gesture;
reusing it in a list costs the list its scroll.

### 6.11 Skeletons

`inset` fill with `animate-pulse`, at the exact height and radius of whatever it stands in for.
Never more than one screenful — three rows is enough to say "loading"; twenty is a lie about
what is coming.

While REFRESHING existing content, keep the old content on screen instead. A list that blanks on
every keystroke reads as "no results", repeatedly.

### 6.12 Empty and no-result

Two different states, two different messages.

- **Empty** — nothing asked yet. Say what this screen can do and give a way in.
- **No result** — something asked, nothing found. Name what was searched and offer the single
  most effective filter to relax. Never a bare "No results."

Both use `EmptyState` (§6.3): dashed hairline, centred, `h4` title, `body-sm ink-600` body.

### 6.13 Segmented control

Two or three mutually exclusive views of **the same list** — "Current / Past", not navigation.
Full width, `radius-pill`, `ink-100` track, 4px inset padding. The selected segment is an
`ink-0` pill on `shadow-sm` with `ink-950` text at weight 600; unselected is `ink-600` on the
bare track. Each segment is a 40px-high target inside a 44px row.

A segment may carry a count after its label in `tabular-nums`; a zero count is rendered, not
hidden, because "Past 0" is information and a missing number reads as a loading state.

Use it only where the segments are the same kind of thing and the user is switching lens. Where
the destinations differ in kind, that is the tab bar's job (§6.7), and where one option is a
filter on a list that has other filters too, use chips (§6.4). Never more than three segments —
at four, the labels truncate at 360px and it becomes a worse tab bar.

Implemented as a `radiogroup`: the selected segment carries `aria-checked`, and selection is
never signalled by fill alone (§8) — the weight change carries it too.

### 6.14 Bottom sheet

The only modal this product has. It rises from the bottom edge, because that is where the thumb
already is (§4) and a centred dialog on a 390px screen is just a card with the page greyed out.

`radius-card` on the **top two corners only**, `page` surface, `shadow-lg`, full width, capped
at 85% of the viewport height with its body scrolling inside. A 36×4px `ink-200` grab handle sits
centred at the top — the affordance that says this can be dismissed downward. Behind it, a
`rgb(0 6 36 / .45)` scrim.

Layout is title (`h3`), optional one-line body (`body-sm ink-600`), content, then actions pinned
at the bottom of the sheet: primary full-width, dismissal as a `ghost` beneath it. Actions never
scroll out of reach.

Dismissal is by scrim tap, Escape, or the grab handle — and **all three mean the same thing**.
A sheet whose scrim tap silently confirms is a trap. Anything destructive or irreversible gets an
explicit button; the sheet closing is always "no".

Enter and exit use `motion-slow` with the sheet translating and the scrim fading; under
`prefers-reduced-motion` both simply appear. `role="dialog"` with `aria-modal`, focus moves to the
sheet on open and returns to the trigger on close.

Use it for a decision that needs context the current screen cannot show — picking which job to
send a pro, confirming a cancellation. Not for navigation, and not for anything with more than one
input: a form belongs on a screen.

### 6.15 Pro profile

What a result row (§6.10) opens onto, and the only screen in the app whose job is *reading*
rather than deciding. It is a pushed screen (§6.6): 44px back chevron top-left labelled with
where it came from, never a bare arrow.

Order is fixed, because it is an argument and the parts only work in sequence: lead photo,
name in `h1`, headline, then one `meta tabular-nums` line of figures — rating, distance, rate,
years, jobs done. The verification line sits directly under it in `go-700` with a shield glyph;
it is the one claim this marketplace is actually selling, so it is never further down the page.

Then titled blocks, each skipped entirely when empty rather than rendered as a heading over
nothing: **Trades** and **Specialises in** as `Tag` pills (§6.4), **About**, **Their work** as a
horizontally scrolling strip, and **Reviews**.

Reviews are a page, not a history. The heading says so — "Showing the most recent of 47" —
because `ratingCount` in the header counts every rating and the list below it never will, and two
numbers that disagree without explanation read as a bug. Each review is a `radius-card` row: 36px
round avatar or initial, author name, five stars filled to the rating, relative date, then the
body. Stars carry their value in the accessible name (§8); an unrated pro gets the `New` pill and
never `0.0 ★`.

The primary action is pinned to the bottom of the screen, not placed after the reviews — a page
of reviews is exactly the length that buries a button (§9). It opens the send sheet (§6.14)
rather than acting directly, because "which job?" is a question this screen cannot answer.

### 6.16 Address field

An address is the only input in this product that must resolve to something real: distance is
what the deck ranks on, so a typed line that never became a coordinate is not an answer.

The §6.9 search field geometry, with a suggestion list below it and a **precision line** beneath
that. Suggestions are §6.10 result rows at 56px, no thumbnail, title plus one `meta` line, and
the list caps at five — a sixth is a scroll inside a form and nobody reads it.

The precision line is the component's whole reason for existing and is never optional:

| State | Line | Tone |
|---|---|---|
| Resolved to a street address | "Matched to <address>" | `go-600` with a check |
| Resolved to a street/area only | "Approximate — we will match from <area>" | `sun-500` with an alert |
| Nothing resolved | "No address yet — matching from <city>" | `ink-600`, no icon |

Never show only a tick. "We found something" and "we found the right thing" are different
claims, and a field that renders them identically is how a placeholder gets stored as a
location.

A "use my current location" control sits below, and on success **must** fill the text with a
reverse-geocoded label — a button that silently sets an invisible pin gives the user nothing to
check.

### 6.17 Join as a pro

The one screen in this product that has to sell something, written under a system that bans
marketing heroes and feature grids (§9). The resolution is that it does not describe the
offer — it **shows the thing being offered**, then asks for an account.

Order is fixed:

1. `overline` kicker, `h1`, one sentence. No stat bar, no logo wall.
2. **The preview.** A non-interactive replica of an incoming job request, exactly as a pro
   would receive it: trade, title, distance, urgency, budget, and the accept/decline pair.
   It is the single raised element on the screen (§5) and it carries `aria-hidden`, because a
   sample is not a control — a screen reader offering a fake Accept button is a trap.
   Label it in visible text as an example; a mock that reads as live data is a lie.
3. **How it works** — an ordered list, three items, numeral in a `brand-500` pill. An ordered
   list, not a grid: these are sequential, and a grid would both break §4 and imply they are not.
4. **What you will need** — the credentials `pro.submitForReview` actually gates on, with the
   same required/optional split the wizard uses. Softening it here to raise sign-ups only moves
   the drop-off to step four, where the person has already spent their time.
5. The primary action, sticky at the bottom (§9).

Every claim on this screen is load-bearing and must be traceable to behaviour that exists.
"We verify ID, insurance and licence" is true; a response time or an earnings figure is not,
and neither is a setup duration nobody has measured. Invent nothing here.

The account note is required, not decorative: `user.setRole` refuses once a job has been
posted, so a customer tapping this is creating a *second* account. A screen that lets them
believe otherwise produces a support ticket at the worst possible moment.

## 7. Motion

| Token | Duration | Easing | Use |
|---|---|---|---|
| `motion-fast` | 120ms | `cubic-bezier(.4,0,.2,1)` | Hover, focus, colour |
| `motion-base` | 200ms | `cubic-bezier(.4,0,.2,1)` | Enter / exit, expand |
| `motion-slow` | 320ms | `cubic-bezier(.22,1,.36,1)` | Page and card transitions |

Transition `color`, `background-color`, `border-color`, `opacity`, `transform` — never `all`.
Non-essential animation is wrapped in `@media (prefers-reduced-motion: no-preference)`. The
deck's drag is essential and stays; its spring flattens under reduced motion.

---

## 8. Accessibility floor

- Body text ≥ 4.5:1, large text and UI borders ≥ 3:1. `ink-500` fails body text — placeholder only.
- Visible focus on every interactive element: `0 0 0 3px brand-200` plus a `brand-500` border.
- Touch targets ≥ 44×44px.
- Colour is never the sole carrier of meaning.
- One `h1` per page, headings in order, no level skipped for size.
- Decorative images `alt=""`; icons inside labelled controls `aria-hidden`.

---

## 9. Do / Don't

| Don't | Do |
|---|---|
| Square-cornered buttons | `radius-pill`, always |
| `brand-500` as a section background | White or `ink-50`; blue for the CTA inside it |
| Grey `#8F8F8F` body copy | `ink-600` for secondary text |
| Positive letter-spacing on headings | `-0.02em` and tighter |

## 10. Where this lives in code

| Concern | File |
|---|---|
| Token definitions (`@theme`), base layer, dark mode | `apps/web/src/styles/globals.css` |
| Font loading, chrome wiring | `apps/web/src/app/layout.tsx` |
| Button, Input, Card, Chip, Banner, Field primitives | `apps/web/src/components/ui/` |
| App bar and tab bar | `apps/web/src/components/chrome/` |

Screens compose primitives. A screen that writes its own `rounded-xl bg-[#...]` has bypassed the
system — fix the primitive instead.
